Earth Science 7- San Salvador, El Salvador

Basic Information

Coordinates: 13˚41'24.00"N 89˚11'27.70"W[1]

Elevation: 2,306ft- Google Earth

Body of Water: Lago de Llopango; Llopango Lake[2]

Climate Zone: Aw or Af [3]

Geology

Plate Name: Caribbean

Closest Boundary Type: Ocean-Continent Subduction[4]

Distance from Boundary: 100mi(200km)[5]

The type of rock underlying San Salvador is metamorphic. This is because the city is very near a subduction boundary, so the existing rock is heated and pressured by the magma and the trench.[6]

San Salvador is a predominantly Low pressure zone; this affects the climate because it causes more precipitation. The low latitude means that it is most probably in a tropic zone; the elevation makes no sense; the topography is mostly flat, meaning no varying climates; its proximity to water means that it will rain alot and the climate will be relatively mild; the ocean currents contribute to the amount of rain, humidity and change in temperature; the prevailing winds, I cannot fully understand what they do; and the plenty of vegetation decreases the CO2 in the area along with adding more O2, to the weather it makes the temperature milder, like the proximity to water.
